Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667648, here are decompositions:
- 7 + 8667641 = 8667648
- 37 + 8667611 = 8667648
- 47 + 8667601 = 8667648
- 89 + 8667559 = 8667648
- 109 + 8667539 = 8667648
- 127 + 8667521 = 8667648
- 137 + 8667511 = 8667648
- 151 + 8667497 = 8667648
Showing the first eight; more decompositions exist.
